3500+ venice wont go above 2.6GHz stable

post #1 of 34
Thread Starter 
I am working on getting my cpu OC'd and would like for it to reach around 2.7GHz on stock cooling but it becomes unstable after about 2.55-2.6GHz, I am keeping my HTT and my ram at stable OC speeds so I am sure that it is the CPU that is the unstable part here, but what I don't understand is why it is becoming unstable at such a low overclock when I have read other people hitting up to 3.0GHz with a 3500+ venice, but my comp won't even post anything past 2.7GHz. I don't think it is the temp. even though I am on stock cooling it still stays around 47°C under full load. Any ideas?

How much voltage are you giving your components? What is your HTT at?

I have tried a lot of different combinations, 270x10, 245-250x11, and I'm using 2.7v-2.75v vDimm and anywhere from 1.5v-1.58v vCore and my mobo maxes out at about 1.58 so I cant go any higher than that. My HTT is being kept below 1000MHz so that cant be the problem, unless having to too low can cause problems because I think I had it a little below 800MHz on some attempts.

Can you bump up your Vdimm anymore? Try it at 2.8-2.85 if you're RAM can handle it. What are the timings at? Are you running a divider?

I'm not sure how much vDimm my ram can handle, I just got it from newegg today and am still kinda fooling around with it but its origional timings are 2-3-2-5 1t, I have it running 2.5-3-2-5 1t to keep it stable at higher MHz, I memtested it at the new settings and it passed at 230MHz one full time through, so I am keeping it at or under 220MHz to be safe and sure that it isnt going to be the cause of my errors so yeah I'm running a divider to keep it somewhere between 200MHz and 220MHz. On newegg it says that its vDimm is 2.6, but thats all it says, it doesnt give a range.

I just looked at the patriot website and it says 2.6-2.7 volts, so I am already running it higher than it recommends I guess.

If the 2.6vdimm you are talking about was on the ram page than it is probably talking about the rams default vdimm voltage. Go into your bios and give the ram more voltage just like you did the cpu. Put it at 2.8vdimm as I am pretty sure all ram can handle 2.8.

EDIT:I saw your edit and you may be running slightly higher but bumping it up to 2.8 should not hurt.

With the Asus MB you will need to be running 2T, which is its default, to have any form of stability over about HT 230-235. It does not affect real-world apps that much.

Work through the A8N FAQ - link in my sig. to see more about this MB.

don't know about that 1t/2t on an asus board, but my 3500+ has the same problem. probably got the same crappy bad proc as i did, you order it from newegg in the last month or so?

I ordered it from newegg in late august, but yeah i tried the 2t thing and set my computer to 250x11 with ram on a 11/14 divider and the cpu wouldnt get past the asus splash screen, bumped it down to 245x11, and it booted but just before the windows load screen it restarted...so that doesn't seem to be helping.

On this MB leave the CPC at 2T esp. over 235... and if you run the mem on a big divider you will then be able to see just where the CPU can go.

If it is failing at 250 try a Vcore bump and also try working up from 245.

CPU cooling will also have an impact and a stock HSF will not get you that far. Try reseating this with some AS5 or change to a 3rd party cooler.
